Now I'm back to the commit 36cf5a. It's the last commit that fast forward and rewind work on my system (Kabylake).

After the changes (Makefile, softhddev.c,softhddev.h and softhddevice.cpp) with the commit df3464b "Add PlayTsVideo function to play TS packets." the problems are same like with the aktual vaapidevice.

Too bad, because the current vaapidevice offers a better presentation.
